Coral Reef Restoration Overview

At Tracc, we are saving the ocean, one coral, one turtle and one shark at a time.

The coral reefs of the world are in serious trouble. They are gradually being destroyed at a rate of 2-3% each year from a wide range of human impacts, from dredging to global climate change, from ocean acidification to destructive fishing. Here at Tracc we work on proactive solutions for coral reef restoration.

Coral Growing

We grow new coral to plant on the reefs we are restoring.

We start by collecting broken coral fragments, which we plant in concrete bases that we call biscuits. We take these to our underwater nursery to grow them into established corals. Once grown, we harvest them and bring them back to our reef, which has been badly damaged by dynamite fishing. We plant them in a bottle reef, where they continue to grow to create a brand new coral reef.

Building Reefs

We build new reefs from recycled bottles, to make a home for fish, organisms and our new corals.

We build sections of bottle reef, which in turn build larger reefs, such as step reefs and ribbon reefs. A bottle reef uses recycled glass bottles collected from the beach to create a 3D underwater structure. Small fish appreciate the vertical structure that lifts them away from the sand, crabs live within the cracks and crevices, and many organisms settle on the bottle surfaces. It also provides a platform for our coral growing.

Slope Stabilisation

We stabilise our slope to prevent our regeneration work slipping away.

Pom Pom Island has a steep slope from the reef crest to the deep water dropoff at a depth of around 50m. All this slope has been seriously blasted in the past by bomb fishermen. All that is left of the original reef are the rubble fragments on a seriously sloping reef. The structures we build are difficult to stabilise.

Biodiversity Surveys

We conduct biodiversity surveys to measure how our work is helping the marine life.

We welcome qualified divers to assist with more challenging diving, from surveys at night, drift dives and big fish surveys to photographing the macrolife.  We want to use your qualified scuba diver skills to help with marine conservation and we will teach you more about the ocean.
